RE: Musiland Monitor 01 USD - late to the party, but...

Maybe, I find it very useful and nowadays very rarely get the Tek analog 'scope out.

So you are looking at the end with the 'scope in 1:1 mode, while I am looking at the beginning with a probe that minimises capacitance. So rather different methodes. Also, mine was powered of the USB bus.

Sorry, I do not follow? How can the sample rate be 100KHz out? I am getting the expected frequencies everywhere. Do you mean 100Hz?

Anyway, I was merely referring to the actual measured behaviour of the SPDIF output, not to the overall performance. What I have found however, is that jitter with the mods I did (01 USD) is low enough that my AP can't show it, which is not very, very low, but lower than many CD-Players/Transports and lower than any PC Audio device I had at hand.

Yes.

At 20 bits, you are on the verge of dynamic range covering fly-farts-at-20-feet to intolerable pain. Really, what more could we need?
